A NTI-RAIL-CREEPING AND RAIL-FASTENING DEVICE.

Specification of Letters Patent. 1 Patented Dec 14, 1920,

Application filed September 27, 1920. Serial No. 413,130.

T 0 all whom it may concern:

Bej itknown that I, PETER G1 PUnLos, a subject of the King of'Greece,resid1ng at nary wooden tie upon which my improved chair or tie-plate 2is secured by means of spikes or the like 3, the plate 2 being pro- SaltLake City, in the county of Salt Lake vlded at its corners with openingsto permit and State of Utah, have invented certain passage of the spikestherethrough. Plate new and useful Improvements in Anti-RaiL Creeping.and Rail-Fastening Devices; and I do declare-the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the ,art to which it appertains to make and use thesame.

This invention relates to an improved rail fastening device sometimescalled a tie-plate, and it has for one of its objects to provide adevice of this class which is of such construction that it will.absolutely prevent creeping and spreading of the rails, thus preventing,to a great extent, accidents which occur from such circumstances.

A further object of the invention is to generally improve upon devicesof this class by producing one of extreme simplicity and durability,which is extremely easy to make use of, extremely eifective inoperation, and comparativelyinexpensive to manufacture.

A still further and extremely important object of the invention is toprovide a device of the above mentioned class which includes a new andnovel locking member which is provided with wedge ribs on its oppositefaces, thus making it possible to use the same locking member in eitherdirection of trafiic.

Other objects and advantages of the invention will be apparent duringthe course of the following description.- 7

In the accompanying drawings forming apart of this specification and inwhich like numerals are employed to designatelike parts throughout thesame: i Figure 1 is a top plan view of the device constructed inaccordance with my invention, the same being shown in use.

Figs. 2 and 3 are sections taken on the lines 2-2 and 3-3 of F ig. 1,respectively, looking in the direction of the arrows.

Fig. 4 is a detail perspective view of the locking member.

Fig. 5 is a bottom plan view of a slightly modified form of the baseplate of my device.

Fig. 6 is a detail sectional view taken on Referring to the drawingwherein the preferred embodlment of my 1nvent1on is (itsclosed, thenumeral 1 designates an ordi- 2 is provided along one edge with anenlarged portion 4 which extends from end -will be provided between theinner edge of the boss and the op osite edge of the base flange of therail. laced u on this boss 7 is a locking member 8 in the mm of a plate,the same being provided with an elongated slot 9 through which aretainingbolt 10 is passed, the bolt being received in the screw,-

threaded aperture of the boss 7 and serving .to clamp the member 8 in aset position. The plate 8 is provided-on its opposite faces adjacent itsinner edge with ribs which are tapered, both in the same direction,these ribs constituting wedges which are adapted to he slid into'thetapered space between the boss 7 and the adjacent edge of thebase flangeof the rail 6 to retain the rail in position. It is to be noted that theinner longitudinal edges of the ribs 11 are undercut so that they willeffectively engage the undercut portion of the boss 7. Attention isdirected to the fact that in case the rail has a tendency to movelongitudinally as it does when it creeps, it will carry the member 8with it and this member thus obtains a more efi'ective wedging'actionand will eventually stop creeping altogether. Thus the member 8 due tothis construction, will be held rigidly in place and will be preventedagainst moving upward as might otherwise occur. Emphasis is to be laidon the construction of the locking member 8 since it is provided withan'elongated slot 9 which permits it to have considerable slidingmovement to obtain the proper wedging action between the ribs and thebase flange I is very either direction of traffic. Thus, the neces: sityof employing two different kinds of locking members is entirelyobviated.

Provision is made for anchoring plate 2 so as to prevent it frombecoming accidentally-displaced and permitting possible spreading andcreeping of the rails as mlght otherwise occur. In igs. 2 and 3 of thedrawing, this anchoring means isshown in the form of a plurality ofV-shaped ribs 12 which are arranged in parallelism to one another on theunderface of the base plate andare adapted to be embedded in the tie 1.In Figs. 5 and 6, I have shown a slightly different constructionofanchoring means. By referring to these figures, it will be noted thatthe anchoring means here shown is in the form of a plurality of diagonalrows of substantially square projections 14. From practical experience,I find that the V-shaped ribs 12 are most advantageous in that they arevery easily embedded in the tieeither by manual exertion or by theweight of the train which is exerted on them. Hence, this form ofanchorlng means useful in that it is very easy to be placed in effectiveposition -on the tie. On the other hand, the type of anti-slipping meansdisclosed in Figs. 5 and,6 is more advantageous in that constantpressure exerted onthe plate from the weight of the passing train willin time embed in the projections in the rail, and when once embeddedthere is little or no chanceof them permitting slipping or creeping ofthe base plate. So, it will be seen that the V-shaped ribs areadvantageous in that they are more easily placed in effective position,but they are not as effective as the other type of anchoring meansbecause there is a chance of them permitting slipping and creeping ofthe device which is not possible with the construction disclosed inFigs. 5 and 6.

In use, the base plates 2 are placed upon the ties in the usual manner,and the retaining spikes 3 are driven through the holes in these platesto secure them to the ties. Then, the railis placed in position on theupper face of the base plate in such a manner as to cause one edge ofthe base flange to become disposed beneath the retaining flange 5 on thebase plate. lVhen the rail is'in this position, a substantially V-shapedspace will be formed between the opposite edge of the base flange of therail and the inner edge of the boss 7. Now, assuming that the retainingplate 8 has been placed on theboss and the bolt 10 passed through theslot therein and into the screwthreaded aperture in the boss in such amanner as to permit the member 8 to slide, the plate is moved in such amanner as to force the narrow end of one of the ribs in the V-shaped sace far enough forward to effectively bin the base flange of the railbeshould be only slightly tightened so member 8 can move to obtaintheabove result.

From the foregoing description, it will be seen that .I have devised anextremely desirable and effective rail securing device which isextremely simple and inexpensive. It is provided with a novel anchoringmeans which absolutely prevents creeping or slipping of the rail anddevice, consequently overcoming the possibility of creeping andspreading of the rails due to accidental movement of the tie plate. Thelocking between the effective wedge rib and inner longitudinal edge ofthe boss prevents accidental upward movement of the locking member 8 andincreases the effectiveness and the rigidity of the device.

A very careful consideration of the foregoing description taken inconnection with the accompanying drawing, will enable persons skilled inthe art to which the invention of the subjoined claim.

I claim:

An anti-creeping rail plate and rail fasteningdevice comprising a baseplate provided with anchoring means and on its upper face and along oneedge with securing means for receiving one edge of the rail base flange,being also provided on-its upper face adjacent its opposite edge with aboss having a screw-threaded aperture extending therethrough, the inneredge of said boss being undercut and inclined from opposite edges toreduce the width thereof at one end, a retaining and clamping plateresting on said boss, being provided with an elongated hole registeringwith said screw-threaded aperture, and also provided on its oppositefaces with wedge ribs having undercut faces to co-act with the undercutportion of said boss, the double wedge ribs permitting the same clampingplate to be used in either direction of traffic, and a clamping boltpassing through the aforesaid elongated hole and into the adjacentscrew-threaded aperture.

In testimony whereof I have hereunto set my hand.

PETER G. PULLOS.
